I'm trying to get my player to lift up a box and then be able to throw it out again.

If you hit the left mouse, the box is pinned to the player's image point.

Once pinned you can unpin it by hitting the right mouse but a second action attached to that event (right clicking the mouse when the object is pinned) should evoke a pysics force 5 and hurdle the box away to a defined position.

Only, the box just unpins, falls to the floor and the physics action is ignored.

Any help on how to make my box get thrown away ? Did I make a mistake using the "pin" behaviour to simulate lifting up the box and keeping it lifted ?

This is the link. For some reason the PNG pics don't show but the if you approch the bigger object with the smaller object you should be able to lift it by clicking your left mouse. The next step should be to throw it away again but if you hit the right mouse it just triggers the "unpin" action, not the physics.

If anybody has a general tip on how to make a player lift up a box an throw it a couple of pixels further away, be happy to hear it.

I didn't open your capx, but reading your explanation it looks like something I encountered a while ago. Basically you need to wait 1 or 2 ticks between the moment you unpin and the moment you apply the throwing force... I think.
